SLDS Bend-Limiting

Bend-limiting tubes such as the Square-Lock Double Spring tube (SLDS) are uniquely designed for protecting large core optical fibers or fiber bundles.

The larger bending radius is achieved by inserting two stainless steel wires into the spiral valley of the square-lock tube, thus limiting the bending characteristics of the tube. It also provides higher durability and robustness to the SLDS tube.
